This tutorial provides a comprehensive guide on creating checkbox and checkbox group components using Vue.js' Composition API, emphasizing the Single File Components (SFC) approach. It begins by detailing how to define props for individual checkboxes, incorporating properties such as value, label, checked state, id, and disabled state. The tutorial explains the use of computed properties to manage class names for dynamically changing the UI based on the checkbox's state and demonstrates how to handle events with defineEmits for custom event management. Additionally, it covers constructing a checkbox group component, where multiple checkboxes can be manipulated collectively, including defining properties, emitting events, and managing state changes using reactive refs. The tutorial also highlights the use of scoped CSS for styling and integrating SVG icons to visually represent the checkbox states. Finally, it showcases how to render these components in an application, providing a practical example of the checkbox group in action, and offers a link to a full Vue project for further exploration.
